Objective:
To enhance the dissolution rate of daidzein with solid dispersion technique.
Method:
Solid dispersions were prepared by the solvent method using water-solubility chitosan as a hydrophilic carrier. DSC, IR and X-ray methods were used to verify the formation of solid dispersion.
Result:
Dissolution percentages of solid dispersions were more than 90 percent in the drug-carrier ratio of 1:5 and 1:9. But dissolution percentages of physical mixtures and pure drug were 40 and 38.4 percent respectively. Part of daidzein dispersed in solid dispersion in the form of microcrystalline.
Conclusion:
Water-soluble chitosan solid dispersion can significantly increase dissolution rate of daidzein.
